Basic Information

A Helium White Dwarf is a form of White Dwarf Star that used to be normal star - possibly even a Solar Analog - but lost it's mass. The most likely cause of such mass loss is from another nearby hotter star (which might cause it to radiate off via photoevaporation, or deprive it of fuel via early gravity effects). The faint little star left behind has the right type of fuel it needs to be a real star, but lacks the proper mass to really get a reaction going.
